Abstract

Object oriented design of operating systems has evolved from pure protection considerations to a more general methodology of design as exemplified in Intel's iAPX-432 machine. This paper compares and contrasts, from an architectural point of view, eight major object oriented operating systems. Five different architectural aspects have been chosen as a basis for this analysis. These aspects include: uniformity of the object approach, object type extensibility, the process concept, the domain concept, and object implementation techniques.
